Helical Spiral Bar 6mm x 1 metre

Details: 6mm x 1 metre

Code: Helical

Helical Spiral bars are designed for crack stitching repairs to masonry walls and brickwork. Helical Spiral bars are installed with either resin or cementitious grout across cracks in a wall to increase the tensile and flexural strength of masonry. The cracked wall is reconnected, tensile forces redistributed along the full length of the bar and the stabilised structure restored to full strength.

Helical Spiral bars provide an effective masonry reinforcement solution for new construction and for remedial work in existing buildings. They are suitable for concrete reinforcement applications as well and offer a strong permanent stainless steel solution.

Uses

• Masonry Bed Joint Reinforcement
• Anti-crack reinforcement around door/window openings
• Provides extra strength in footings, parapets and retaining walls
• Suitable for certain types of thin pre-cast concrete sections such as pre-cast panels and pre-cast doors and window details

Advantages

• Helical Spiral Bars can be cut to any length on site
• Corrosion resistant
• Can be easily bent into any shape
• Suitable for a wide range of uses in new construction and remedial work

Notes
This system is suitable for conventional brickwork and rendered/plastered walls.  Vertical spacing is normally every 4 to 6 brick courses (300-450mm), however this should be checked with the structural engineer.  Where cracks are within 500mm of corners or reveals the bar should be bent and bonded 100mm around the corner.  If two or more cracks are close together, bars can be lapped.  Laps should be at least 500mm and the bar should extend 500mm from the outer cracks.

Important
It is essential that the cause of the cracking is established by a structural engineer and then eliminated, prior to the installation of this system.
